vdB 158

VDB 158 is a faint reflection nebula in the constellation Andromeda that seemingly undergoes an odd, 90-degree bend. The overall shape of the brighter part is similar to an axe or hatchet. VDB 158 is part of the larger area of nebulosity LBN 534.

LBN 534 is an isolated and elongated molecular cloud in the constellation of Andromeda. Either shock fronts from a supernova or ionization fronts from a massive star could have caused the shape of this cloud as well as the spatial distribution of young stars. The blue reflection nebula, vdB 158, is located at the southern end of the cloud. The nearby bright B9.5V star, HD 222142, illuminates VdB 158.

Also visible in this image is the tiny planetary nebula PLN 110-12.1. Good luck finding it!

This photograph is comprised of 267 5 minute exposures, calibrated and stacked, for an image consisting of 22.25 hours of exposure.

I sincerely hope you enjoy this image.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
